Abstract (sommario):

Neurotransmitters are chemical messengers that play an important role in the nervous system’s control of the body’s physiological state and behaviour. Abnormal levels of neurotransmitters are closely associated with some mental disorders. Therefore, accurate analysis of neurotransmitters is of great clinical importance. Electrochemical sensors have shown bright application prospects in the detection of neurotransmitters. In recent years, MXene has been increasingly used to prepare electrode materials for fabricating electrochemical neurotransmitter sensors due to its excellent physicochemical properties. This paper systematically introduces the advances in MXene-based electrochemical (bio)sensors for the detection of neurotransmitters (including dopamine, serotonin, epinephrine, norepinephrine, tyrosine, NO, and H2S), with a focus on their strategies for improving the electrochemical properties of MXene-based electrode materials, and provides the current challenges and future prospects for MXene-based electrochemical neurotransmitter sensors.

Abstract (sommario):

Neurotransmitters are chemical compounds released by nerve cells, including neurons, astrocytes, and oligodendrocytes, that play an essential role in the transmission of signals in living organisms, particularly in the central nervous system, and they also perform roles in realizing the function and maintaining the state of each organ in the body. The dysregulation of neurotransmitters can cause neurological disorders. This highlights the significance of precise neurotransmitter monitoring to allow early diagnosis and treatment. This review provides a complete multidisciplinary examination of electrochemical biosensors integrating nanomaterials and nanotechnologies in order to achieve the accurate detection and monitoring of neurotransmitters. We introduce extensively researched neurotransmitters and their respective functions in biological beings. Subsequently, electrochemical biosensors are classified based on methodologies employed for direct detection, encompassing the recently documented cell-based electrochemical monitoring systems. These methods involve the detection of neurotransmitters in neuronal cells in vitro, the identification of neurotransmitters emitted by stem cells, and the in vivo monitoring of neurotransmitters. The incorporation of nanomaterials and nanotechnologies into electrochemical biosensors has the potential to assist in the timely detection and management of neurological disorders. This study provides significant insights for researchers and clinicians regarding precise neurotransmitter monitoring and its implications regarding numerous biological applications.

Abstract (sommario):

Current electrophysiology and electrochemistry techniques have provided unprecedented understanding of neuronal activity. However, these techniques are suited to a small, albeit important, panel of neurotransmitters such as glutamate, GABA and dopamine, and these constitute only a subset of the broader range of neurotransmitters involved in brain chemistry. Surface-enhanced Raman scattering (SERS) provides a unique opportunity to detect a broader range of neurotransmitters in close proximity to neurons. Dynamic SERS (D-SERS) nanosensors based on patch-clamp-like nanopipettes decorated with gold nanoraspberries can be located accurately under a microscope using techniques analogous to those used in current electrophysiology or electrochemistry experiments. In this manuscript, we demonstrate that D-SERS can measure in a single experiment ATP, glutamate (glu), acetylcholine (ACh), GABA and dopamine (DA), among other neurotransmitters, with the potential for detecting a greater number of neurotransmitters. The SERS spectra of these neurotransmitters were identified with a barcoding data processing method and time series of the neurotransmitter levels were constructed. The D-SERS nanosensor was then located near cultured mouse dopaminergic neurons. The detection of neurotransmitters was performed in response to a series of K⁺depolarisations, and allowed the detection of elevated levels of both ATP and dopamine. Control experiments were also performed near glial cells, showing only very low basal detection neurotransmitter events. This paper demonstrates the potential of D-SERS to detect neurotransmitter secretion events near living neurons, but also constitutes a strong proof-of-concept for the broad application of SERS to the detection of secretion events by neurons or other cell types in order to study normal or pathological cell functions.

Abstract (sommario):

Background: Accumulating evidence indicates that the gut microbiota can synthesize neurotransmitters as well as impact host-derived neurotransmitter levels. In the past, it has been challenging to decipher which microbes influence neurotransmitters due to the complexity of the gut microbiota. Methods: To address whether a single microbe, Bifidobacterium dentium, could regulate important neurotransmitters, we examined Bifidobacteria genomes and explored neurotransmitter pathways in secreted cell-free supernatant using LC-MS/MS. To determine if B. dentium could impact neurotransmitters in vivo, we mono-associated germ-free mice with B. dentium ATCC 27678 and examined fecal and brain neurotransmitter concentrations. Results: We found that B. dentium possessed the enzymatic machinery to generate γ-aminobutyric acid (GABA) from glutamate, glutamine, and succinate. Consistent with the genome analysis, we found that B. dentium secreted GABA in a fully defined microbial media and elevated fecal GABA in B. dentium mono-associated mice compared to germ-free controls. We also examined the tyrosine/dopamine pathway and found that B. dentium could synthesize tyrosine, but could not generate L-dopa, dopamine, norepinephrine, or epinephrine. In vivo, we found that B. dentium mono-associated mice had elevated levels of tyrosine in the feces and brain. Conclusions: These data indicate that B. dentium can contribute to in vivo neurotransmitter regulation.

Abstract (sommario):

Neurotransmitters are chemicals that act as messengers in the synaptic transmission process. They are essential for human health and any imbalance in their activities can cause serious mental disorders such as Parkinson’s disease, schizophrenia, and Alzheimer’s disease. Hence, monitoring the concentrations of various neurotransmitters is of great importance in studying and diagnosing such mental illnesses. Recently, many researchers have explored the use of unique materials for developing biosensors for both in vivo and ex vivo neurotransmitter detection. A combination of nanomaterials, polymers, and biomolecules were incorporated to implement such sensor devices. For in vivo detection, electrochemical sensing has been commonly applied, with fast-scan cyclic voltammetry being the most promising technique to date, due to the advantages such as easy miniaturization, simple device architecture, and high sensitivity. However, the main challenges for in vivo electrochemical neurotransmitter sensors are limited target selectivity, large background signal and noise, and device fouling and degradation over time. Therefore, achieving simultaneous detection of multiple neurotransmitters in real time with long-term stability remains the focus of research. The purpose of this review paper is to summarize the recently developed sensing techniques with the focus on neurotransmitters as the target analyte, and to discuss the outlook of simultaneous detection of multiple neurotransmitter species. This paper is organized as follows: firstly, the common materials used for developing neurotransmitter sensors are discussed. Secondly, several sensor surface modification approaches to enhance sensing performance are reviewed. Finally, we discuss recent developments in the simultaneous detection capability of multiple neurotransmitters.

Abstract (sommario):

In the CNS, minor changes in the concentration of neurotransmitters such as glutamate or dopamine can lead to neurodegenerative diseases. We present an evolutionary perspective on the function of neurotransmitter toxicity in the CNS. We hypothesize that neurotransmitters are selected because of their toxicity, which serves as a test of neuron quality and facilitates the selection of neuronal pathways. This perspective may offer additional explanations for the reduction of neurotransmitter concentration in the CNS with age, and suggest an additional role for the blood-brain barrier. It may also suggest a connection between the specific toxicity of the neurotransmitters released in a specific region of the CNS, and elucidate their role as chemicals that are optimal for testing the quality of cells in that region.

Abstract (sommario):

Concentration is very important and needed for children in following the learning process. learning concentration can be seen from an increase in the presence of neurotransmitters. Neurotransmitters function as chemical messengers that play an important role in information processing throughout the nervous system. The purpose of this research is to describe the Literature Study: A Biopsychological Review in Improving Children's Concentration. This research uses library research with a qualitative descriptive approach. Based on the results of the review of 25 (twenty-five) journals examined by the author, there are various effectiveness of neurotransmitter performance involved in various brain functions, such as sleep, mood, emotion, attention, and learning and memory. The conclusions of this study include: 1) Neurotransmitter metabolites include biogenic amines (catecholamines norepinephrine, epinephrine, and dopamine and serotonin) and amino acids (glycine, glutamate, and γ-aminobutyric acid [GABA]), 2) Serotonin is useful for neurotransmitters and concentration, 3) Neurotransmitters including acetylcholine play an important role in the development of brain nerve structures and cells. Acetylcholine (ACh) is the first identified cholinergic neurotransmitter, and changes in its content can fully reflect the growth and development of the body as well as learning ability and memory, 4) Students who are able to concentrate during lessons will have higher memory and easily understand what is learned and 5) The researcher suggests that future studies examine the effect of one of the various types of neurotransmitters on children's concentration and motivation to learn.

Abstract (sommario):

Neuronal transmission relies on electrical signals and the transfer of chemical signals from one neuron to another. Chemical messages are transmitted from presynaptic neurons to neighboring neurons through the triggered fusion of neurotransmitter-filled vesicles with the cell plasma membrane. This process, known as exocytosis, involves the rapid release of neurotransmitter solutions that are detected with high affinity by the postsynaptic neuron. The type and number of neurotransmitters released and the frequency of vesicular events govern brain functions such as cognition, decision making, learning, and memory. Therefore, to understand neurotransmitters and neuronal function, analytical tools capable of quantitative and chemically selective detection of neurotransmitters with high spatiotemporal resolution are needed. Electrochemistry offers powerful techniques that are sufficiently rapid to allow for the detection of exocytosis activity and provides quantitative measurements of vesicle neurotransmitter content and neurotransmitter release from individual vesicle events. In this review, we provide an overview of the most commonly used electrochemical methods for monitoring single-vesicle events, including recent developments and what is needed for future research.

Abstract (sommario):

In this study, we found that esketamine significantly increased the cortical concentration of multiple neurotransmitters in mice. However, esketamine dynamically simplified the overall network of cortical neurotransmitters at different behavioral states during the perianesthesia period. The concentration of 5-HT in the medial prefrontal cortex (mPFC) was highly correlated with the esketamine-increased gamma oscillation. These findings suggested that the transformation of the neurotransmitter network rather than the concentrations of neurotransmitters could be more indicative of the consciousness shift during esketamine anesthesia.

Abstract (sommario):

Neurotransmitters are the body's chemical transmitters. Their task is to send nerve cell messages to target cells. The target cells might be found in muscles, glands and other nerves. In order to control many of the processes needed for the brain, it needs neurotransmitters including: heart rate, respiration, circadian rhythms, digestion. The nervous system regulates the organs, psychological and physical operations of the individual. The neurotransmitters of nerve cells, also known as neurons, have a substantial function. The cells of the nerves fire impulses. This is done by the release of neurotransmitters, chemical substances that relay signals to other cells. Each neurotransmitter binds to another receptor — for instance, dopamine molecules attach to the receptors of dopamine. This initiates action in the target cells when they are coupled. The body eliminates or recycles them after neurotransmitters send their messages.

Abstract (sommario):

P2X receptors are fast, ATP-gated cation ion channels. To date seven subtypes of P2X receptors have been cloned and identified, PZXH. The membrane topology of the P2X subunit consists of intracellular amino- and carboxy-termini, two transmembrane spanning domains and a large extracellular loop. Despite similar membrane topology, within this family of receptors the P2X subtypes possess different functional characteristics. They exhibit different sensitivities to agonists and antagonists, are modulated differently by extracellular ions, and have different pore forming abilities. The regions that are responsible for differences in function between P2X subtypes have not been elucidated. This thesis aims to further knowledge regarding the relationship between the structure of the P2X family and differences in the function of the various receptor subtypes. Examination of the primary structure of the P2X receptor family led to the identification of epitope regions suitable for antibody production. This suite of antibodies was tested for specificity and the distribution of P2X receptors was examined in a range of rat tissues and two cell lines. The pathophysiological involvement of the P2X7 receptor was examined in B-CLL patients. Two polymorphisms as well as a loss of function mutation were identified in both normal and leukaemic populations. The site of agonist binding is believed to be within the extracellular loop. Examination of the primary structure of the human cytolytic receptor P2X7 led to the identification of two noncontiguous regions that could potentially be involved in binding ATP. Three amino acid residues that lie within the extracellular loop were targeted and their involvement in ATP binding was determined. Two lysine residues at positions 193 and 31 1 and a proline residue at 210 were each exchanged with alanine. An abolition of function of human receptors with mutations at positions 193 or 311 was observed, consistent with a disruption of the ATP binding domain, although alterations in transduction or gating cannot be dismissed. The P2X receptor appears to be comprised of a trimeric subunit arrangement, and Hill coefficients of between 1 and 3 reported for ATP binding suggest that there is more than one ATP binding site per functional receptor. Modelling of the putative binding cleft of the hP2X7 subunit was performed and the residues important for ATP binding were highlighted. The fimctional trimeric receptor appears to possess three intersubunit ATP binding sites. In an attempt to isolate regions of the extracellular domain that contribute to or control various channel properties, chimaeras between subtypes P2X], P2X4 and P2X7 were constructed and their properties examined. Each of the six chimaeras has been shown to be correctly inserted into the cell membrane and functional. These constructs will continue to be investigated and form the basis for extensive future work.

Abstract (sommario):

Fluorescent analogs of biomolecules have been known as useful probes to study the structure, conformations and dynamics of cellular processes. These probes are more ideal than fluorescent labeled probes, as fluorescent analog probes retain the shape, size, conformation, and recognition element of the natural substrate, while giving useful intracellular information about detection and dynamics of biomolecules. The monoamine neurotransmitters control the central and periphery nervous systems. Serotonin (5-HT), in particular, is a versatile chemical messenger responsible for a multitude of biological processes, such as regulation of emotion, vasoconstriction, and bone metabolism. The study of serotonergic complex pathways is vital and essential in drug discovery for the diseases that result from the depletion and deregulation of serotonin in synapse. The extracellular concentration of serotonin is controlled by several transporters, most preferably the serotonin transporter (SERT). Selective serotonin reuptake inhibitors (SSRIs), along with dual- and triple-acting inhibitors, affect SERT and hence 5-HT in depression and related diseases. In this present investigation, firstly, a set of fluorescent analogs of neurotransmitter probes based on ethylamino-functionalized substrates were successfully designed and these fluorescent probes were synthesized by convenient synthetic methods. Secondly, optical properties of these fluorescent probes were investigated in organic medium, in order to test their suitability for screening and imaging the biological cells. Finally, their uptake was examined in the murine osteocytic cell line, MLO-Y4, platelets of blood sample and HEK-293 cells expressing the dopamine transporter (DAT), norepinephrine transporter (NET) or SERT. The fluorescent probes targeting bone-derived cell line expressing 5-HTT provide useful information in understanding the dynamics of 5-HT regulation with respect to SSRI treatment. A novel fluorescent analog of 5-HT probe was developed that may be utilized to study 5-HTT function in the context of 5-HT uptake or regulation in cell culture, tissue explants, or even in vivo.

Abstract (sommario):

Three studies on the relationship between food, hormones and neurotransmitters are presented for this thesis. In the ﬁrst study, a series of three experiments was conducted in 33 healthy human ratio volunteers. The aim was to investigate the effect of carbohydrate meals on the plasma of tryptophan (trp) to the sum of 5 other large neutral amino acids (LNAAs ) (trp: LNAA ratio). Synthesis s of serotonin, the brain neurotransmitter, depends on availability of its precursor trp from the bloodstream. Animal models have shown that the plasma trp:LNAA ratio, provides an index of trp uptake by the brain and of subsequent serotonin synthesis. A carbohydrate meal may increase the ratio because the elicited insulin response promotes selective uptake of the competing LNAAs into peripheral tissues. The first hypothesis was that carbohydrates with differing insulin responses would produce corresponding alterations in the size of the up:LNAA ratio response. The second hypothesis was that the trp:LNAA ratio response to a given carbohydrate meal would be greater in the evening compared to the morning. Different test meals were isoenergetic and presented in random order to each volunteer on separate occasions. Plasma glucose, plasma insulin and plasma LNAAs were measured sequentially for 4 h after each meal. In the first experiment, different carbohydrates (sucrose, glucose or potato+bread) (64 g), were given at breakfast time as part of a mixed meal with added protein (25 g) and fat (17 g). No rise in the plasma up:LNAA ratio occurred after any of these meals. Protein, by providing relatively more of the competing LNAAs than of wyptophan counteracted any effect of carbohydrate on the ratio response. Therefore it is unlikely that carbohydrate eaten in the average mixed meal would influence serotonergic activity in the brain. In an attempt to maximise the ratio response, the carbohydrate portion in the second experiment, (sucrose or raw starch) was increased to 120 g; fat and protein were omitted. Plasma insulin and plasma glucose peaks were higher after sucrose than after raw starch (p<0.01) and the ratio rose correspondingly higher, by 34% after sucrose and by 20% after raw starch (p<0.05). In the third experiment the same test meals in the second study were given in the evening after standard meals during the day. Compared to the morning, evening plasma glucose and insulin responses were more sustained, although peak heights were not markedly different.

Abstract (sommario):

Organic electronic materials, that is, carbon-based compounds that conduct electricity, have emerged as candidates for improving the interface between conventional electronics and biological systems. The softness of these materials matches the elasticity of biological tissue better than conventional electronic conductors, allowing better contact to tissue, and the mixed ionic-electronic conductivity can improve the signal transduction between electronic devices and electrically excitable cells. This improved communication between electronics and tissue can significantly enhance, for example, electrical stimulation for therapy and electrical recording for diagnostics. The ionic conductivity of organic electronic materials makes it possible to achieve ion-specific ionic currents, where the current consists of migration of specific ions. These ions can be charged signalling substances, such as neurotransmitters, that can selectively activate or inhibit cells that contain receptors for these substances. This thesis describes the development of chemical delivery devices, where delivery is based on such ion-specific currents through ionically and electronically conducting polymers. Delivery is controlled by electrical signals, and allows release of controlled amounts of neurotransmitters, or other charged compounds, to micrometer-sized regions. The aims of the thesis have been to improve spatial control and temporal resolution of chemical delivery, with the ultimate goal of selective interaction with individual cells, and to enable future therapies for disorders of the nervous system. Within the thesis, we show that delivery can alleviate pain through local delivery to specific regions of the spinal cord in an animal model of neuropathic pain, and that epilepsy-related signalling can be suppressed in vitro. We also integrate the delivery device with electrodes for sensing, to allow simultaneous electrical recording and delivery at the same position. Finally, we improve the delay from electrical signal to chemical delivery, approaching the time domain of synaptic signaling, and construct devices with several individually controlled release sites.

Abstract (sommario):

Neuroscience is an “umbrella” concept which incorporates more scientific domains that permit the accomplishment of transdisciplinary study at the crossroads of biochemistry, physiology, and psychology. The theoretical study concentrates on the analysis of several scientific point of views and research of the main 3 hormones/ neurotransmitters, which define the characteristics of human personality situated in the brain and the spinal cord, serotonin, dopamine, and norepinephrine. The above-mentioned hormones/neurotransmitters have beenm studied through the prism of biochemistry and physiology, however, much less through that of psychology. More studies have proven the direct connection between the variation of an individual’s personality and the levels of neurotransmitters present in the system. The previously stated facts highlight the necessity of deepening this study, especially in the domain of correlation between the abundance/absence of a certain hormone/neurotransmitter in the human body and the traits of personality.

Abstract (sommario):

Dopamine is an important neurotransmitter belonging to the catecholamine family, which acts on the central nervous system. This catecholamine plays a key role in regulating a variety of functions, such as motor and cognitive functions. This class of neurotransmitters is important for normal neurophysiology and is also the target of a broad spectrum of therapeutic and illicit agents. Evaluating the interaction of these neurotransmitters, in particular, dopamine with water molecules, is crucial for a better understanding of the conformational preferences of dopamine in solution, which consequently assists in the design of new drugs for the treatment of diseases associated with a malfunction of the system, and direct measurement, which is particularly essential for early warning of certain diseases. In this sense, the objective of this work is to examine the effects of aqueous solvation on the geometric and electronic parameters of dopamine using Car-Parrinelo Molecular Dynamics. The Car-Parrinello Molecular Dynamics simulation was performed using the CPMD program package (Version 4.1). The results indicate that dopamine interact swith several water molecules, with the formation of hydrogen bonds. In particular, there are two hydrogen bonds (H5···Owf and N3···Hwd) with an infinite residence time that strongly suggests the protonation of these groups.

Abstract (sommario):

Alcohol addiction is a serious problem that affects millions of people and costs individuals, families, and communities a lot of money. It can disrupt the brain's chemistry and cause a person to lose control of their behavior. Recent advancements have shed light on the role of several neurotransmitters in the disease of alcoholism. Various neurotransmitters have been linked to alcohol addiction because of a brain imbalance, which could be caused due to excessive activity or inhibition. The dopaminergic, serotoninergic, gamma-aminobutyric acid (GABA), and glutamate pathways are among the brain circuits known to be altered by alcohol consumption. Importantly, attention deficit hyperactivity disorder (ADHD) is also characterized by poor impulse control. Furthermore, Methylphenidate is used to treat ADHD by regulating dopamine and other neurotransmitters, also affected by alcoholism. The purpose of this review is to look into the future use of Methylphenidate in the treatment and prevention of alcoholism. This review supports the future use of Methylphenidate in the treatment and prevention of alcoholism. However, more clinical research on the effects of Methylphenidate is required.
